Cilla & Rolf Börjlind - Spring Tide

When police college student Olivia Rönning is offered an old unsolved murder case as a class assignment, she can't resist it, and any plans she had for the summer break are soon put on hold as she is drawn into a complex mystery involving a pregnant woman buried alive on a Nordkoster beach almost thirty years ago. Meanwhile, the local police are preoccupied with a recent spate of shocking assaults on the homeless that are making headlines – not least because each attack has been filmed and uploaded quite blatantly to the internet.

Spring Tide is an impressive thriller; immersive and intelligent, with sinister villains, surprising twists and a likeable, resourceful investigative team. Swedish writing duo Cilla and Rolf Börjlind are crime fiction veterans, and it shows in the intricate plotting and the nimble way they flit between a huge cast of characters without ever letting the story become incoherent.

Though it's possible that their writing style will not be to everyone's taste. The Börjlinds are fond of clipped sentences.

And one-line paragraphs.

While these are often very effective in selling the drama, sometimes they seem more like involuntary narrative tics. This is a minor quibble however, and you almost certainly won't care once their story has its hooks in you.
